SZPEOI'ZFICATION forming part of Letters Patent No. 640,450, dated January 2, 1900.

Application filed September 8, 1899- Serial No. 729,825. (No model.)

To aZZ who/7t it may concern:

Be it known that l, JOHN P. ORONIN, a citi-= zen of the United States, residing in Paterson, county of Passaie, and State of New Jersey, have invented an Attachment for finding- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of this specification.

This invention has reference to machines for winding silk or other filaments from swifts onto bobbins. in machines of this nature at present in use no means is provided for determining or measuring the amount of material that is wound onto the bobbins, and since the attendant has to depend alone upon the comparative appearance of the bobbins when wound in order to determine whether theycontain even approximately the quantity of material intended some bobbins are often wound with considerably more and some with considerably less than that quantity.

The object of this my present invention, therefore,is to provide a simple and efficient means for measuring the material as fast as it is fed onto the bobbins.

A further object of the invention is to pro-- vide means for automatically stopping the feed of the material onto each bobbin at such times when the winding of the quantity predetermined has been completed.

The invention consists in an attachment for winding-machines whereby the quantity of material wound upon the bobbin from the swifts may be measured and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter pointed out, and finally embodied in the clauses of the claim.

The invention is fully illustrated in the accompanying drawings, whereinmeasuring attachment mounted thereon. Fig. a is a sectional view, slightly enlarged, through a certain indicator-block and show ing in elevation a revoluble feed-screw connected therewith. Figs. 5 and G are enlarged transverse sectional views on the lines so and y 3/, respectively, in Fig. 8; and Fig. 7 is an enlarged view in elevation of a modified form of indicator-block, showing in section a revoluble feed-screw which actuates it.

In said drawings, a designates the upper central rail of a winding-machine, and Z) designates one of a pair of other rails or beams that are disposed at both sides of the rail a and extend, like said rail a, throughout the length of the machine.

0 designates one of two or more bearingbrackets in which is journaled the driveshaft d, carrying friction-wheels c and oper' ated from a suitably-driven shaft f through bevel-gearing g.

h denotes other brackets that are secured to the rail b and project therefrom over the brackets 0, having notches c', that provide bearings for the trunnion of the bobbinsj and adapted to support the reciprocating rod 70, upon which are mounted the thread-guides Z.

m indicates the swift-hangers. Each of said swift-hangers consists, as usual, of a bar a, having integrally formed therewith at one of its ends an attaching-plate 0 and at the other of its ends a hook-shaped bearing socket 1), wherein is adapted to rest one of the trunnions q of a swift r. The bar projects at an incline from the attaching-plate and is secured thereby to the rail a in such a manner as to bring its bearing-socket approximately beneath the bobbins and the neighboring parts in the usual manner.

My attachment may be described as follows: 3 indicates an elongated metallic casing which is substantially semicylindrical in shape in cross-section and which is provided with integral oppositely-disposed attaching fingers or lugs 25, preferably at each of its ends. The casing also has preferably integral end walls a, and it is adapted to be secured to the bar a with the edges of said end Walls in contact with one of the faces of said bar, the fingers tbeing forced around the edges of the bar and clamped against its other face. In the walls a of the casing is journaled a feed screw U, said feed-screw having a collar to and a nut z for maintainingit in its bearings in the casing. The lower end of this feedscrew projects beneath the lower end wall of the casing, and it carries a star-wheel a, that is adapted to be engaged by a tappet or finger b, that is attached onto one of the spokes of the swift. Thus each time the swift revolves said tappet engages one of the points of the star-wheel, so as to impart a partial revolution to the feed-screw. The casing is provided with a longitudinal slot 0, and adjacent said slot its outer face is marked off in a series of graduations e, which-may be numbered consecutively or otherwise indexed, as required, preferably beginning at the bottom of the casing.

e designates the indicator block. Said block consists of a sleeve member f, which incloses a shoe g, in which shoe is swiveled the inner end of a spindle h, that is screwed into and projects through the sleeve and has its outer end bent off at an angle and formed into a knob i. The sleeve is penetrated by the feed-screw c, and it should be remarked that the face of the shoe which is adjacent to the feed-screw and also the opposing portion of the interior surface of the sleeve are threaded, so as to engage the threads of said feedscrew. Thus when the spindle h is manipulated in an obvious manner, so as to bring its threaded surface and the threaded portion of the interior surface of the sleeve in engagement with the threads of the feed-screw, an operative engagement between the indicatorblock and the feed-screw will be effected, whereupon when the latter is rotated the former will move longitudinally thereon.

The lower end of the slot 0 is provided with a communicating notch or recess j, formed in the casing. The friction between the indicator-block and the feed-screw will tend to maintain the spindle h against one side or edge of the slot 0, and it is on this side of the slot that the recess j should be formed, for a reason hereinafter more particularly eX- plained.

In Fig. 7 I have shown a modified form of the indicator-block, which consists of a clip that is shaped to partially surround the feed-screw, and a lever Z, which is fulcru med on a spindle m (corresponding to the spindle h) and is provided with a shoe n (corresponding to the shoe 9') at one of its ends and is actuated by a spring 0 at the other of its ends to maintain the shoe in contact with the feedscrew. It should be remarked that portions of the surface of both the clip and the shoe which contact with the screw should be threaded to engage the latter the same as in the case of the indicator-block first described.

In operation, one of my attachments being secured to each of the swift-hangers, as hereinbeforesufficiently described, and the indi Gator-block being set at that mark on the graduated scale d which indicates the number of yards of material which the respective bobbin is to contain, as the revolving bobbin draws upon the swift through the medium of the thread which is being wound from one onto the other the swift will be rotated, its tappet Z) striking against the points of the star-Wheel, and thus rotating the feed-screw. As the feed-screw rotates the indicator-block will move downwardly toward thelower end ofthe casing. When it has moved far enough so that its spindle is opposite the recessj, (the friction between the block and the feedscrew tending to force the spindle in the direction of the recess,) said spindle will enter the same. Thereupon its knob will be projected into the path of one of the spokes of the swift, the impact of which will thus stop the rotation of the swift, and consequently the feed of the material will be automatically cut off at that point where the desired quantity has been Wound upon the bobbin. It is of course necessary that the spindle project far enough so as to efficiently engage one of the spokes of the swift at the proper time.

It will be apparent that although I have hereinbefore described my attachment with referfence particularly 'to its adaptability for use in connection with a winding-machine the device is also applicable to other machines where it is necessary or desirable to measure the material being placed on bobbins, rollers, or in any other manner wound.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a thread-winding machine, the combination of asuitably-sustained swift-hanger, a swift carried thereby, a measuring instrument or indicator adapted to be operated by the swift, and a knob or finger actuated by the measuring instrument and to be thereby projected into the path of the swift to stop rotation thereof;
